Dropping python 2.7 support

[alejandroautalan]

Hello all.
I'm working on plugins to allow pygubu designer to use widgets from external projects.

Some of them are:

• ttkwidgets
• ttkbootstrap (wishlist)

The latest versions of this projects support python3 only (and some python3 specific versions).

So I want to clean the codebase and also maybe, jump to a minimal python3 version.

Is there a minimal python version that you people recommend?

Regards
Alejandro A.

Actually for my own projects I wouldn't support python versions older than 3.7, but I know that there are people using Pygubu with much older Python versions, so 3.7 wouldn't be a good choice.
I don't think Pygubu should support versions older than 3.4, and the code would be much more modern this way. With 3.4 you can also use the pathlib module, which is fantastic!

Hello,

Similar to @rdbende, I also wouldn't use any version older than 3.7 for my own projects. One big milestone, in my opinion, was Python 3.6 which introduced f-strings (v3.6 came out in 2016). I use f-strings regularly. So my vote would be for at least Python 3.6 because of f-strings. However, I would be fine with v3.4 too.

Thanks,

Hello @rdbende and @jrezai, thanks for your comments.
I also like libpath and fstrings. I'll do some more research but I think version 3.6 will be the one to choose.

Thanks!
